Why people keep reordering it
- Researched strains
- Specific, studied strains at counts high enough to reach your gut.
- Guaranteed live cultures
- Potency held through the end of shelf life, not just at manufacture.
- Digestive balance
- Supports regularity, bloating and a healthy gut barrier.
Best suited to: wants strain breadth over one big number, willing to take two or three capsules, rebuilding after a gut disruption, has fridge space and takes it at home.
What the research supports
One capsule holds 12 billion cfu across twelve Lactobacillus and Bifidobacterium strains, unevenly dosed. It ships in the fridge and the bottle is 120 capsules.
Most single-strain probiotic trials use 1 to 10 billion cfu of one organism.
- Digestive comfort (evidence: moderate, from randomized controlled trial, meta-analysis)
- Multi-strain Lactobacillus and Bifidobacterium blends have decent human trial support for regularity and general digestive comfort, though results vary a lot by strain and by dose.
- Gut recovery (evidence: moderate, from randomized controlled trial, meta-analysis)
- Lactobacillus rhamnosus and casei are among the better studied species for helping gut bacteria re-establish, usually at counts higher than what one capsule of this twelve-strain blend gives per strain.
- Feeding bacteria (evidence: moderate, from randomized controlled trial, meta-analysis)
- Fructooligosaccharides and inulin are fibres that Bifidobacterium ferment in the colon, a well-documented prebiotic effect, though the amount in one capsule is small next to a real fibre dose.

Is it right for you
Worth it if
- Wants strain breadth over one big number
- Twelve strains across Lactobacillus and Bifidobacterium cover more of the gut than a single-strain capsule at the same total count.
- Willing to take two or three capsules
- At three a day the total reaches 36 billion and most strains land at 3.6 billion, which is inside the range strain-specific trials use.
- Rebuilding after a gut disruption
- The mix spans small intestine Lactobacillus species and colon-dwelling Bifidobacterium, so it does not stack everything into one region.
- Has fridge space and takes it at home
- These are refrigerated cultures, and kept cold the labelled counts are what you actually swallow.
Look elsewhere if
- Someone who wants a travel or desk probiotic
- This one requires refrigeration. A spore-forming Bacillus coagulans or Bacillus subtilis product holds its count at room temperature and in a bag.
- Chasing one specific researched strain
- If a named strain is the reason you are buying, get that strain on its own at the count its trials used. Here it would be sharing a capsule with eleven others.
- Sensitive to fermentable fibres
- The capsule includes fructooligosaccharides and inulin, which some people react to with gas or bloating. A probiotic without added prebiotic fibre avoids that entirely.
What to expect
Digestive changes from a probiotic build rather than arrive. Give it two to four weeks of daily capsules before deciding. Some people notice more gas in the first few days, partly from the fructooligosaccharides and inulin, and it usually settles within a week. The 120 count is 40 days at three capsules or four months at one.
How it compares
- Compared with a single-strain probiotic at 10 billion cfu
- Twelve organisms instead of one, spanning both the Lactobacillus and Bifidobacterium genera, plus prebiotic fibre in the same capsule. The tradeoff: No individual strain here gets near 10 billion at one capsule a day, so you trade a trial-level dose of one organism for small doses of many.
- Compared with a shelf-stable 50 billion cfu multi-strain capsule
- Refrigerated cultures do not have to be over-filled at manufacture to survive a warm shelf, so the count on this label is closer to what is in the capsule at the end of its life. The tradeoff: It has to live in a fridge, so it is useless for travel and easy to forget when it is not sitting beside the kettle.
